What is G-Express Service?

G-Express service provides dedicated network-based Internet application acceleration service and low latency streaming service to global users. With this, you can provide one-stop OTT live streaming service for content creators and improves user experience by minimizing packet loss and service delivery delays for Internet application services.

G-Express The service consists of a global application acceleration service and a live transcoding service.

Global Application Acceleration Service

Global application acceleration service provides cloud dedicated network-based application acceleration service and live ultra-low latency streaming service to global service areas in need of quality improvement.

This enhances the global user experience of application services such as live streaming, online games, smart offices, and online education.

System Configuration

To use the global acceleration service, the service provider should have the global accelerator (Accelerator). Global Accelerator consists of a listener and an endpoint, and the data requested by the customer's Internet application service user is accelerated and transmitted through the Global Accelerator (Accelerator).

Listener

This is a software module that composes the accelerator and plays a role of accelerating the user's request data received from the listener to the backend server. The customer should have an endpoint in the region where the backend server that requires global application acceleration is located.

Endpoint

This is a software module that composes the accelerator and plays a role of accelerating the user's request data received from the listener to the backend server. The customer should have an endpoint in the region where the Backend Server that requires global application acceleration is located.

Live Transcoding Service

The live transcoding service conveniently allows creating a video stream with the optimal resolution and quality so that the original live video can be played on various user terminals on the Internet and provides a video streaming service without buffering or interruption regardless of the user's network connection environment. In addition, it provides live ultra-low latency streaming service in conjunction with global application acceleration service.

System Configuration

Customers should have a live transcoder to use the live ultra-low latency streaming service. The live transcoder consists of a transcoder and a live streamer and provides a live ultra-low latency streaming service along with a global accelerator.

Transcoder

Live Transcoding: It receives the original live video and converts the video resolution and quality in real time so that it can be played on various end-user devices.

Re-streaming: The original live video obtained is re-transmitted to the existing OTT platform (for example, YouTube, Twitch, Naver TV). DVR allows recording and storing real-time live streaming video.

Live Streamer

It packages the converted live video for Internet transmission and transmits it as HTTP-based streaming. Also, it provides live ultra-low latency streaming transmission along with global application live acceleration service.

Application

Live Streaming Service

In the case of live content creation or Internet live streaming provided by content providers, there is a delay of about 10 to 15 seconds for service users to watch live content after live streaming is transmitted according to HTTP's live streaming protocol. G-Express' ultra-low latency streaming service improves the user quality of Internet live streaming services by reducing the difference between Internet live streaming transmission and user viewing time to less than 3 seconds.

Global Game Acceleration Service

When a global game service user accesses a remote game server, service quality may vary depending on the region the user connects to. These differences in service quality by region of global service users create an unfair service environment among game users. The global acceleration service provided by G-Express is an acceleration service through a dedicated network between the global service user access area and the game server, guaranteeing equal service quality among countless game users worldwide.

Smart Office Acceleration Service

When an on-premises office operated by a global company transforms to a cloud-based smart office, service quality degradation frequently occurs in global regional offices due to smart office service access through a dedicated network with the head office. In this case, you can significantly improve the quality of smart office services in global regional offices by opening global acceleration services between global regional offices and smart office services.
